Direct Measurement of Electric-Field-Induced Birefringence in a Polymer-Stabilized Blue-Phase Liquid Crystal Composite

Abstract

We demonstrate a method to directly measure the electric-fieldinduced birefringence of a polymer-stabilized blue-phase liquid crystal \201PSBPLC\202 composite. The induced birefringence follows the extended Kerr effect well and is approximately 3X the ordinary refractive index change. The measured data are validated by comparing the simulated and measured voltage-dependent transmittance with an in-plane switching cell. The impact of these results to the material optimization of emerging BPLC displays is discussed.
